Superfluidity
Superfluidity is a state of matter that occurs at extremely low temperatures, where a fluid can flow without viscosity or resistance. This means it can move through tiny openings or around obstacles without losing energy. Superfluids exhibit unusual behaviors, like climbing up the walls of their container. This phenomenon arises from quantum mechanics, where particles behave as a single coherent entity. Helium-4 is a well-known example; when cooled to near absolute zero, it transforms into a superfluid, showcasing the fascinating interplay between temperature and quantum effects in low-temperature physics.

Superfluidity is a state of matter where a substance, usually a liquid like helium, flows with zero viscosity. This means it can move without losing energy or slowing down, exhibiting unique behaviors such as climbing up walls and flowing through tiny openings with ease. In this state, the atoms act in unison, almost like a single entity, allowing for these remarkable properties. Superfluidity occurs at extremely low temperatures, close to absolute zero, where quantum mechanical effects dominate the behavior of the particles involved. It challenges our conventional understanding of fluid dynamics.
